NOJB686M006RWJ

Overview

The KYOCERA AVX NOJB686M006RWJ is a surface-mount niobium oxide capacitor from the OxiCap NOJ series. It offers a capacitance of 68 µF with a DC voltage rating of 4 VDC and a tolerance of ±20%. The component features an ESR of 1.5 Ohms and operates within a temperature range of -55°C to +105°C. Packaged in a 1210 (3528 metric) SMD case, it has a maximum leakage current of 5.4 µA and supports a ripple current of 261 mA.

Feature Summary

• Utilizes niobium oxide technology for fail-safe performance and high reliability.
• Provides low equivalent series resistance (ESR) suitable for high-frequency applications.
• Features a compact 1210 surface-mount package design.

Applications

• Mobile phone circuits
• Personal digital assistants (PDAs)
• Laptop computers
• Portable electronic devices

Procurement Notes

Verify the specific voltage rating and case size against the schematic requirements, as the NOJ series includes variants with different ratings such as 6.3V or 10V. Confirm that the 1210 footprint matches the PCB land pattern. Ensure the application environment stays within the specified -55°C to +105°C operating temperature range to maintain performance integrity.

Selection Notes

Select this component when a lower cost alternative to tantalum is required without sacrificing reliability. The niobium oxide construction prevents catastrophic failure modes associated with tantalum capacitors. Choose this part for space-constrained designs needing high volumetric efficiency in the 1210 package form factor.

Part Context

This capacitor belongs to the OxiCap NOJ series manufactured by KYOCERA AVX. The series is designed to replace tantalum capacitors in various consumer electronics applications. It provides a robust solution for decoupling and filtering in portable devices where size and safety are critical constraints.

Replacement Considerations

Direct substitutes include other niobium oxide capacitors from the same manufacturer family with matching capacitance and voltage ratings. Verify that any replacement maintains the 1210 case size and similar ESR characteristics to ensure circuit compatibility.
